Effect of Bacillus baekryungensis YD13 supplemented in diets on growth performance and immune response of sea cucumber (Apostichopus japonicus)

Effects of dietary Bacillus cereus G19, B. cereus BC-01, and Paracoccus marcusii DB11 supplementation on the growth, immune response, and expression of immune-related genes in coelomocytes and intestine of the sea cucumber (Apostichopus japonicus Selenka)

“…Many studies have been reported AKP and ACP take part in immune defense of aquatic animals [51e53]. In the present study, AKP activity of coelomocytes was significantly enhanced in three probiotics treatment groups, and this result was similar to those reports in sea cucumber [54,55] and Rainbow trout (Oncorhynchus mykiss) [56]. SOD is the important component of antioxidant defense system of the organism [57].…”

Effects of combined dietary administration ofRhodotorulasp. H26 andBacillussp. BC26 on growth, immunity and intestinal microbiota in juvenile sea cucumber,Apostichopus japonicus

“…and Bacillus spp. has been proved to improve the phagocytosis and/or respiratory burst of coelomocytes (Li et al, ; Liu et al, ; Wang et al, ; Yang et al, ; Zhao et al, ), and lysozyme activity and/or phenoloxidase activity of coelomic fluid in sea cucumbers (Li et al, ; Liu et al, ; Wang et al, ; Yan et al, ; Yang et al, ; Zhang et al, ). Recent studies have showed that different expression patterns of immune related genes in coelomocytes, intestine, and body wall of sea cucumber were induced by different species of probiotics (Li et al, ; Yang et al, ), suggesting the different immune regulatory mechanism of different probiotics.…”

“…It has been demonstrated that probionts in Rhodotorula and Bacillus can be effective growth promoters in aquaculture species (Li et al, 2015;Navinchandran et al, 2014;Wang et al, 2015;Yan, Tian, & Dong, 2014b;Yang et al, 2015Yang et al, , 2015aYang, Wu, Jian, & Zhang, 2010;Zhang et al, 2017;Zhou et al, 2016). In the present study, sea cucumbers fed with HB diet exhibited improvement in growth compared to those fed the BD or H diet.…”

“…and Bacillus spp. in sea cucumber aquaculture have focused on the increased non-specific immune parameters after receiving a single strain/species probiotic treatment Wang et al, 2015;Yan et al, 2014b;Yang et al, 2015Yang et al, , 2015bZhang et al, 2017;Zhao et al, 2012Zhao et al, , 2016. Oral administration of Rhodotorula spp.…”

“…and Bacillus spp. has been proved to improve the phagocytosis and/or respiratory burst of coelomocytes (Li et al, 2015;Liu et al, 2013;Wang et al, 2015;Yang et al, 2015Yang et al, , 2015bZhao et al, 2012Zhao et al, , 2016, and lysozyme activity and/or phenoloxidase activity of coelomic fluid in sea cucumbers (Li et al, 2015;Liu et al, 2013;Wang et al, 2015;Yan et al, 2014b;Yang et al, 2015b;Zhang et al, 2017). Recent studies have showed that different expression T A B L E 4 Survival of the probiotics in the intestine of sea cucumbers fed with the basal diet (BD), 1 × 10 8 cells/kg H26 (H), 1 × 10 10 cells/ kg BC26 (B), and 1 × 10 8 cells/kg H26 plus 1 × 10 10 cells/kg BC26 (HB) for 4 and 8 weeks…”
